FILE-FABRIC Loom.

SPECIFICATION forming part of Letters Patent No. 782,494, dated February 14, 1905.

Application filed December 1901. Serial No. 236,647.

in the county of Philadelphia and'State of Pennsylvania, have invented-certain new and usetul Improvements in Pile-Fabr1c Looms, of which the following is a SpBCIfiOQtlOH, reference being had therein to the accompanying drawings, forming a part thereof.

Our invention relates to pile-fabric looms, and more particularly to such looms in which longitudinal pile-wires are employed.

One of the objects of our invention is to provide means for restricting or preventing lateral vibration or displacement of the pile- Wires.

A further object is to provide means for guiding the rear ends of short pilewires which enter the reed-spaces during the forward movement of the lay, so as to cause such rear ends to properly enter the reed-spaces.

Another object of our invention is to provide means for causing the guiding means to recede from the spaces between the pile-wires at each beat of the lay, thereby avoiding interference with the pile-loop-forming operation and also with the reed. K

We will now describe the loom embodying our invention illustrated in theaccompanyingdrawings and will thereafter point out our invention in claims.

Figure 1 is a longitudinal vertical section of such parts of the loom as are required for an understanding of our invention with the lay in an intermediate position. Fig. 2 is a similar view of the parts of the loom adjacent to the lay, the latter being in extreme forward position. Fig. 3 is a detail vertical elevation of the reed and adjacent parts looking toward the breast-beam or front of the loom and broken away at middle portions thereof.

The figuring-warps a, b, a, d, and e are controlled by figuring-harness comprising harness-cords 11, which would be actuated by suitable jacquard or other mechanism, so thatthe pile-forming threads are raised to form the pile and lowered to enter the shed while the lay is in forward position. The binder warp-threads f and 9 may be controlled by suitable heddles. (Not shown.)

The lay 5 is carried on swordsi6 on a rockshaft 7 and is actuated by arms 8 in any suitable manner. The laycarries the usual reed 9, whicl1 may be of any usual or suitable construction. a crossing-reed 10 of the construction fully shown in and covered by patent to Nathaniel Marcus Shinn, No. 733,434, dated July 1 1, 1903, andwhich need not, therefore, be particularly described. Any suitable Warp-crossing mechanism may be provided to perform the function of causing the pile-warps to be looped over the pile wires. Longitudinal pile-wires are shown of the construction covered by Patent No. 730,438 to Thomas Benton Dornan, dated June 9, 1903, these pilewires 12 being supported by a stationary cr0ss bar18ii1 front ofthe reed and projecting rearward and being of such length as to penetrate the reed only when the reed is in forward position, so that the reed in moving backward moves entirely clear of the pile-wires and in moving forward approaches and overlaps the pile-wires, the rear ends of the pile-wires entering and penetrating the reed-spaces.

The guiding means for the pile-wires comprise'a guide member 1 1, provided with downwardly-extending teeth 15, shown as tapering at their lowerends and of such length as to project into-the spaces between the pile-wires and hold the pile-wires in alinement when the guide member is in its extreme rearward position, as shown in Fig. 1. This guide member'is movable and is shown as provided with guide-rods 16, located at the sides of the loom and at the ends of the guide member and slidable in stationary guide-sleeves 17, extending rearward from a suitable supporting cross-bar 18, which. is rigidly supported in the loom. Retractive means are providedfor the guidemember, shown as coiled springs 19 surround- The lay is also shown as carrying ing the rods and sleeves and tending to move 25, carried by the guide member and interposed.. in the path of the reed, so as to be engaged by the reed and moved forward by the reed, carrying the guide member forward and compressing the springs 19. The guide-sleeves 17 are slightly inclined downward and rearward relatively to the pilewires, so that the forward movement of the guide member is also an upward movement thereof, and as the guide member is'moved' upward the teeth thereof are carried upward, so that their ends are raised clear of the pilewires, and the pile-wires are unobstructed by such teeth and may freely receive the pileloops formed thereon by-the weaving mechanism. The location of the teeth 15 of the guide member and of the contact-piece 25 is shown as such that the contact-piece meets the reed at about the same time that the rear ends of, the pile-wires meet the reed, so that the guide-teeth direct the rear ends of the pile-wires into the reed-spaces and are then moved rearward and upward, 'so as to leave the pile-wires unobstructed for the pile-forming operation. Fig. 1 shows the guide member in the position of the engagement of the contact-piece 25 and the reed 9. Fig. 2 shows the reed in extreme forward position, with the guide-teeth 15 so lifted as not to obstruct the pile-forming operation. Upon the backward movement of the lay the guide member is impelled by its springs 19 so as to follow the reed until the guide member reaches its extreme rearward position, (shown in Fig. 1,) the guide-teeth 15 moving downward and rearward and entering the spaces between the pile-wires and guiding the pile-wires to proper alinement, and at the extreme rearward position of the guide members the guide-teeth hold the rear ends of the pile-wires in alinement, and they are maintained in such posi tions until the reed again approachesthe guide member and the pile-wires enter the reedspaces. Thus the rear ends of the pile-wires are guided and held in proper positions at all times when they are out of the reed-spaces, and their proper entrance into their proper reed-spaces is assured during each beat-up of the lay. It will also be observed that the guide-teeth recede gradually fromthe spaces between the pile-wires, and thus perform their guiding function until the pilewires have entered a suitable distance into the reed- 5 tion and lhat various modifications may be made in the construction shown and above particularly described within the principle and scope of our invention.
